Compaitibility of 2.1mm to 2.5mm barrel adapter (ADA2897)

2.1mm to 2.5mm DC Barrel Plug Adapter
SKU: ADA2897


I believe I am in need of the above product. However, i just want to
make sure this will work with my power switching adapter for my usb hub.

I just purchased

However, i must have measured the tip incorrectly because it doesn’t
fit, and comparing the AUS version to the US version I have, the Inside
diameter of the AUS tip is indeed slightly smaller.

Will this adapter work with a positive tip? I’m not that educated on
polarity, I just know this is a positive tip device and the actual tip
is metal and black whereas your item is pictured with a tip that is
metal and white. I don’t even know if that makes a difference.

thanks for you help

Hey Shark,
This looks like the exact product you need. It will fit into a device that would normally require a 2.5mm plug, and lets you use a 2.1mm plug. The polarity with just be replicated with the adapter; meaning it’s definitely compatible!

Good luck with it!

Cheers Mate! Thanks for the clarification
